IMPROVEMENT IN CORN-SHELLERS The Schedule referred to in these LettersPatent and making part of the same To all whom it may concern Be itknown that I, ,HAnMon W. CORNELL, of Owego, in the county of Tioga, andState of New York, have invented a new and improved Oorn-Sheller; and Ido hereby declare that the following is a full and exact description ofthe construction and operation of the same, reference being had to theaccompanying drawings making part of this specification, in which-Figure 1 is an elevation of the top of the machine, showing thearrangement of its gearing;

Figure 2 is a vertical elevation of the front side;

Figure is a vertical section through the receivingtube; and

Figure 4 is-a transverse section of receiving be, througlrwhich cornpasses, the two shelling-cylinders, and spring.

The nature of my invention consists in placing two cylinders,constructed as hereinafter described, paral-. lel to and near eachother, both turning in the same direction, but one moving at a greatervelocity than the other, and are so arranged that as a springholds earsof corn against both cylinders, the one moving slowest allows them toturn, while the fastest-running cylinder strips off the corn, and alsodraws the ears through the machine. To enable others skilled in the artto make and use my invention, I will describe its construction andoperation.

On a suitable frame is hung a shaft, n, on one end of which is a wheel,A, which has two rows of teeth or cogs, one set of cogs about half thedistance from the centre to the outside of the wheel, and the other setat its periphery.

Engaging in each of these series of teeth are small pinions, on the endsof horizontal shafts d It.

Shaft d, which turns with the greatest velocity,

while the machine is in operation, extends across to the opposite sideof the machine, where, on the end projecting beyond the frame, is fixedthe fiy-wheel G.

On shafts d k, which are parallel to each other, and on the inside ofthe frame B, are small bevel or mitre-gears c c, fig. 1, which engage insimilar gears or "wheels, on two vertical shafts directly under shaftspractically covered with spiral hooked teeth.

Thev vertical shafts have each a cylinder, D E, which are parallel andclose to each other. One cylinder E is simply corrugated its entirelength, while the other c'ylinderD has narrow grooves surrounding it,leaving short elevated portions between them, and these elevations arealso corrugated, but the corruga tions are spiral, and the surface ofthis cylinder is (See figs. 3 and 4.) i"

A receiving-tube, H, formed in a wooden block, F, I conducts ears ofcorn down between the shafts d and k, to the cylinders, while a spring,0, inside the tube presses them into the angle formed by the cylinders,

to be'acted upon by both in the process of shelling.

The spring 0 (figs. 3 and 4) does not force corn against both cylindersequally, but is turned (fig. 4)

in such a manner'as to force-the corn hard against the cylinder D, whilethe motion of this cylinder presses it sufficiently hard againstcylinder E.

The spiral teeth on cylinder 1) areinelined in such a direction thatthey draw ears of corn through the machine, while the length of thecylinders is sure toremove all corn from the cob, and their smalldiameter,'allowing the work to be done near the centre of motion,greatly lessens the power required to use the machine. I

What I claim as my invention, and desire to secure by Letters Patent,isp 1. The combination of cylinder E, corrugated as described, andcylinder D, constructed with grooves and spiral corrugations, as shown,said cylinders being arranged parallel to one another, and running atdif--' ferent velocities, for the purpose specified.

2. The arrangement of wheel A, shafts n d k, and fly-wheel O,incombination with the corrugated shelling-cylinders D and E, whenconstructed and arranged in the manner and for the purpose hereinspecified. HARMON W. CORNELL.
